r/Seeed_Studio

Does Carlos drink enough water? Seeed Studio sent me their human presence detecting kit, and I decided to use it on my cat. I'm sure that's not what they intended, but that's their problem, not mine. I'm using an ultrasonic sensor and PIR motion detector in a 3D printed enclosure to sense when my cat drinks, and roughly how much.

This was also an excuse to experiment with ESPHome on battery power, over OpenThread. It didn't go perfectly, but that's what experiments are for. The video covers the build, and the blog posts cover the software side also.

Presenting inx on sticky, an ereader firmware.

Maximizing the device full potential and having great features.

• Images looks great
• Can zoom in images
• Bookmarks/Highlights/Dictionary
• Can add notes to page/highlights through mic + ai
• Search & filters and multi list view
• Books renders really well, like having a mini book in your pocket
• Customizable home screen with widgets

Coming soon...

I’ve developed custom firmware for the Seeed Studio Sticky that turns this little e-paper device into a life counter for Magic: The Gathering.

The firmware is completely free and can be flashed directly onto the Sticky using the r/Seeed_Studio Seeed Studio Playground. So there’s no need to install anything or compile the firmware yourself — all you need is the Sticky itself.

A huge thank you to limengdu, who has already merged my firmware into the Community Playground!

The firmware is and will remain free and not for sale. You only need to buy the device from Seeed Studio — everything else is free.

What do you think of the idea? Would you use a little e-paper life counter like this at the game table?

If you use my affiliate link to purchase your Seeed Studio Sticky, you’ll be supporting me and the continued development of this project — at no extra cost to you.

I enjoyed my development with the reTerminal E1002 so much that I decided to buy and create a variant for the reTerminal E1004.

In that case, I use it to display personal pictures, photographs by other authors (organized by theme), and works of art.

In my case, reTerminal E1004 simply connects to a URL on my server. It's there that I've programmed a backend that allows me to organize the content to be displayed (personal pictures, image of the day, artwork of the day, and a lot more...).

In other words, in my specific case, reTerminal E1004 acts as a web viewer, with content hosted on my own server.

Hello. I've decided to post here something I originally shared months ago on the Seeed Discord server. It's a personal project I created with reTerminal E1002 (color). I hope you like it and that it inspires others.

Based on the weather conditions in my city, together with indoor temperature and relative humidity data from my home, the data representation is now accompanied by dynamic images. Depending on the value of the data, some elements are highlighted in yellow to warn about cold, heat, rain, or wind.

Thanks to AI, a matrix of cat pictures has been generated for the outdoor cat, covering different seasons of the year and weather conditions. The same has been done for the indoor cat, shown at different times of the day. As a result, the terminal is now able to illustrate and present the data in a more fun and surprising way.

And one extra detail: the lighting both outdoors and indoors changes according to sunrise, daytime progression, and sunset… tinting the background with different colours. In this case, I'm using a personal web server (PHP, JS + HTML, CSS). The home's temperature and humidity data are sent to the server, which stores them. The E1002 simply visits a page on the server that makes up the entire view. Part of the functionality is in PHP and part in JS (you could also use Node).

The interesting thing is that you'll have to apply some tricks, since the web rendering speed on the E1002 is limited (unlike on a desktop PC). It's best to do the final image composition (built from overlapping layers) on the server side to provide the device with a pre-composed, small-sized image (.webp).

The color offers new possibilities and forces me to improve the pages to make them even more beautiful. I've named my device "gatino" (gato + arduino) in spanish, wich in english is something like "catino" (cat + arduino).

A color e-paper display is especially useful for showing weather maps with color gradients. The device has a dithering algorithm that helps reproduce photos and full-color images in a realistic way.

The device displays many other views that I have programmed: famous quotes, my agenda, clock, calendar, weather forecast for the next few hours and days, nearby webcams, riddles, trivia, personal photos, famous paintings, cultural agenda and much more.

I am fresh in the area of of microcontrollers.

Although I have started it previous year but never did it continuously,

Recently I have built a project an offline bluetooth based audio transferer( if this name makes any sense). I have explained it here : https://www.youtube.com/watch?v=TobbYyqOm7s

Guys can you feedback me regarding it (like what should i do better) and what should I try to do next....

Appreciate it
